Honorable Federico Pena 8 December 1993 Secretary of Transportation 400 Seventh Street, S.W. Washington, D.C. 20590 Dear Mr. Secretary: I am pleased to announce that Navstar Global Positioning System (GPS) has achieved its Initial Operational Capability configuration as defined in the 1992 Federal Radionavigation Plan jointly issued by our Departments. The Department of Defense hereby makes available to the Department of Transportation the GPS Standard Positioning Service (SPS) in accordance with our Memorandum of Agreement on civil use of the GPS. A signal specification for the SPS, signed by the Chairman of our DoD Positioning/Navigation Executive Committee, is being forwarded to the Chairman of the DOT Navigation Council under separate cover. This is an important and long-awaited milestone in our implementation of the GPS to further Administration goals for expanding dual-use technology. I look forward to continuing, long-term cooperation between our Departments as national and international use of GPS grows. Sincerely, /s/ Les Aspin * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * GPSIC NOTE: We will notify you on how to obtain the GPS Signal Specification when it becomes available.
